Scourge The YTMND parasite (thefticus totalfuckingasshatcoli) is the very worst of all YTMND epidemics. Although rare, this parasite feeds on pre-existing YTMNDs and resubmits them as sites of their own making. Users infected with this parasite beleive that stealing from other YTMND users is ok. Parasites rarely offer sound and image origins because they have stolen it from other sites, and revealing the origin would result in its exposure to the light, and light is what kills Parasites, also vaccines.
VaccinesThere is no known cure from Parasites. All YTMND users are free reign to this plague. The only defense is to label the site a "Parasite", if it is known to be stolen from another submission. The difference between the "Parasite", and a NARV site, is that the Parasite infects its own host, and it doesn't take images from outside sources.
What you can doBe sure to let infected Parasite users know they are carrying the virus by telling them their site is a "Parasite", and notifying the proper authorities. Original sites that are victim of the parasite are immune to the virus.
